I've been experiencing a strange problem with Windows 7 (64-bit) in that after booting up, the wireless is sometimes shut off by Windows (with a little announcement that pops up from the bottom-right-corner; sometimes two or three of these appear at the same time but usually only one). If I don't click the "Dismiss" button quickly enough, I get disconnected and then have to re-enable my wireless NIC.

For web sites and other connection-less protocols, this is not a big deal, but with an SSH session (e.g., via PuTTY) it becomes a very big annoyance as I have to re-connect those as well.

My laptop is connected to AC power, and the power management is set to run in high-performance mode with AC.

Is this a laptop? If so, what brand?

Yes, it's a laptop. It's one of those custom built all-Intel ones (I got tired of the nonsense with major vendors including an endless stream of pop-ups and weird drivers that include enormous GUIs just to display a fancy on/off switch wrapped up in some vendor's logo that hog all spare resources and slow everything down, and have found this to be a good solution). So, the wireless B/G/N NIC is also made by Intel (along with the motherboard, CPU, etc.). I suspect this is a Windows 7 function that I'm dealing with as I've seen this on other laptops with different brands of components.
